STRAINER OF FLUIDIZED-BED ACTIVE CARBON WATER TREATING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a strainer of a fluidized-bed active carbon water treating device by which falling of active carbon particles can be prevented at the time of waste water treating operation and exchanging operation of active carbon particles and active carbon particles can be dropped at the time of classification preventing operation and further in which a strainer main body and a hat-like member have strong bonding strength with each other. SOLUTION: The strainer 22 has structure with which the strainer can be easily fitted and is less prone to fall owing to a taper-shaped upper end part of a strainer main body fitting part 48 and a groove 50B of the hat-like member 42. Further since it is formed so that an angle formed by a horizontal plane and a line connecting a top end of the hat-like member 42 and an opening 44 of the strainer main body 40 is an angle of repose of active carbon particle in water±0.5°, falling of the active carbon particles can be prevented at the time of waste water treating operation and exchanging operation of the active carbon particles and further the active carbon particles can be dropped at the time of classification preventing operation.
